Description
Petitella bleheri has a laterally compressed body with a maximum standard length of 3.6 cm (1.4 in). It can be told apart from the other species in the genus Petitella by having a much more intense and widespread red color in the head, this reaching the humeral region; by having a longitudinal black bar at the end of the caudal peduncle which does not extend far forward; and by having a hyaline anal fin with no black bar.
Range & habitat
Petitella bleheri is found in South America, where it occurs in the middle rio Negro, and from the upper and middle rio Orinoco basins in Brazil, Colombia and Venezuela. It is found in both clear and blackwater tributaries in flooded forests.
What it does
Petitella bleheri feeds on algae and zooplankton, and specimens taken from the Rio Negro have had plant matter and detritus in their guts.
In human culture
Petitella bleheri is classified in the genus Petitella. This name suffixes the Latin diminutive -ella onto the surname of the French zoologist and anatomist Georges Petit, who was director of the Laboratoire Arago in France. The specific name, bleheri, honors the species' discoverer, the German explorer and fish trader Heiko Bleher.
